Descripción
More than 450 stars hosting planets are known today but only
approximately 30 planetary systems were discovered around stars beyond
the Main Sequence. The Pennsylvania-Toruń Planet Search, putting
an emphasis on extending studies of planetary system formation and
evolution to intermediate-mass stars, is oriented towards the
discoveries of substellar-mass companions to a large sample of evolved
stars using high-precision radial velocity technique. We present the
recent status of our survey and detailed characteristic for ~350 late
type giant stars, i.e. the new results of radial velocity analysis and
stellar fundamental parameters obtained with extensive spec-troscopic
method. Moreover, in the future we will make an attempt to perform the
statistical study of our sample and searching the correlations between
the existence of substellar objects and stellar atmospheric parameters
according to previous works which investigated the planetary companion
impact on the evolution of the host stars.
